The bird's mouth joint has been a favorite of wooden boat builders for decades, allowing the construction of hollow masts that are incredibility light and strong. In recent years this simple joint made at the router table had been embraced by furniture and cabinet makers looking to simplify all types of mitered joinery from coopered round columns to mitered cabinet corners. The bird's mouth joint provides three distinct advantages over a traditional miter joint.

  • First, it is fast and accurate requiring only one edge of each workpiece to be profiled.
  • Second, the nesting effect of the joint greatly simplifies workpiece alignment during glue-up.
  • Third, the resulting joint is incredibly strong due to its increased glue surface and joint geometry.

The Infinity Tools Bird's Mouth Router bits are available in three sizes allowing you to make projects with 30°/60° joints (6/12 sides), 45°joints (8 sides), and 22.5° joints (16 sides). Infinity Tools now offers setup blocks for all three bird's mouth Router Bits (sold separately) eliminating guesswork and making setup a breeze. Choose the 3-Pc. Bird's Mouth Router Bit Set 00-570 and get all three router bits plus all three setup blocks for one low price.

Lucy ★★★★★

Finally got around to using these for a mast build, and the clean, consistent bevel on each pass is exactly what I needed. The carbide tips are holding up great through several board feet of white oak.

Elizabeth ★★★★★

I've been using these router bits to build a lightweight mast for my skiff, and the bird's mouth joint came out clean with hardly any tear-out. The carbide tips held their edge through a dozen glue-ups without dulling.

Olivia U. ★★★★★

Finally, a bit that makes those hollow mast sections come together cleanly without the constant chattering I got from cheaper sets. The 1/2" shank gives it real stability through the cut, and the bird's mouth profile is exactly as crisp after a dozen joints as it was on the first pass.
